Results for Q4 2012 Championship

Thirty-two players competed in the Q4 2012 championship. This was our smoothest competition to date; only player experienced a minor problem and our reviewers did such a great job that no errors were found in our quizzes - a significant accomplishment given the complexity of the quizxes.

You will find below the rankings for the championship; the number next to the player's name is the number of times that player has participated in a championship.

Stelios' victory is impressive in two ways: first, he submitted his answers in under 15 minutes, much faster than anyone else (and still achieved 100% correct). Second, he took first place in the Q3 2012 championship. That's quite a track record!

Congratulations to everyone who played in the playoff. I hope you found it entertaining, challenging and educational. And for those who were not able to participate in the championship, you can take the quizzes next week through the Practice feature.

Warm regards, Steven Feuerstein

Note 1: You may wonder how two players can achieve the same % correct and yet the player with the slower time is ranked ahead of a person with a faster time. This can happen due to the fact that the % correct is cumulative across all quizzes in the competition, but you receive a higher score for correct answers on advanced quizzes, compared to intermediate and beginner quizzes. This championship had 4 advanced quizzes and 1 intermediate quiz.

Note 2: Below the table of results for this championship, you will find another list showing the championship history of each of these players.
